Using NDK to Call C code from Android Apps

Android NDK (Native Development Kit) allows working with native C code using a shared C library. It includes the entire toolchain needed to build for your target platform (ARM). Native C code accessible via JNI still runs inside the Dalvik VM, and as such is subject to the same life-cycle rules that any Android application lives by. The advantage of writing parts of your app code in native language is presumably speed in certain cases.
